Feds Probe Concealed Hazard Present in Numerous Range Rovers | Carscoops

      The NHTSA, currently conducting an investigation, reports no known accidents or injuries linked to the front suspension issue.

      It has been noted that the front steering knuckle could potentially detach entirely from the brake assembly.

      The NHTSA has received 12 Vehicle Owner Questionnaires concerning this possible problem.

      In 2017, JLR recalled two of its models due to a similar suspension knuckle joint issue.

      Fears regarding a potential defect in a steering component have led to a new inquiry involving over 91,000 Range Rover Sport vehicles. The U.S. National Highway Traffic Safety Administration (NHTSA) has initiated a preliminary assessment following various reports from owners about a problem with the front steering knuckle. Although no recall has been issued yet, this type of assessment frequently represents the first major step towards that possibility.

      The agency notes that certain 2014 to 2017 Range Rover Sport SUVs might develop cracks in the upper joint of the aluminum front steering knuckle assembly. So far, 12 Vehicle Owner Questionnaires have been submitted detailing this issue.

      Complaints indicate that the front steering knuckle can break at the connection point with the upper control arm ball joint, which is held in place by a pinch bolt and nut. This concern extends beyond aesthetics.

      The steering knuckle is crucial as it supports both the front wheel and the entire front brake assembly. A failure in this area could cause the upper suspension arm to detach, greatly increasing the risk of an accident.

      The investigation encompasses a total of 91,856 Range Rover Sport SUVs from the 2014-2017 model years. To date, there have been no incidents of crashes, fires, injuries, or fatalities related to cracked knuckle assemblies.

      This is not the first occurrence of a similar problem for JLR. In early 2017, the company recalled the 2016-2017 Range Rover Evoque and Land Rover Discovery Sport models, revealing that the lower control arm-to-knuckle joints might have been over-torqued. JLR then stated that if the fastener failed, the wheel knuckle could separate from the lower control arm assembly of the front suspension.

      The ongoing evaluation by the NHTSA is expected to take several months. Meanwhile, owners of the affected vehicles should remain updated with information directly from the NHTSA. While no definitive action has been taken yet, the results of the investigation could result in additional measures, including a recall if safety concerns are validated.
